Description

Technical Field

[0001] The invention belongs to the technical field of waste silicone rubber recycling, and in particular relates to a waste silicone rubber recycling and processing system. Background Art

[0002] Silicone rubber is a rubber material with a main chain composed of alternating silicon and oxygen atoms, and two organic groups are usually attached to the silicon atom. Silicone rubber has good low-temperature resistance. Ordinary silicone rubber is mainly composed of silicon-oxygen chain segments containing methyl and a small amount of vinyl. Silicone rubber is mostly used in automobile tires. With the popularization of automobiles, waste tires are also produced in large quantities. In order to avoid the pollution of silicone rubber to the environment after use, the recycling of waste silicone rubber is particularly important. When recycling waste silicone rubber, most of them are simply crushed to utilize silicone rubber crumbs.

[0003] There will be certain dust and impurities inside and outside the waste tires. When crushed, these dust and impurities will diffuse in the processing environment, causing environmental pollution and being easily inhaled by operators, causing certain harm to the operators. In addition, the dust and impurities will be mixed into the crushed silicone rubber, which will also affect the subsequent use.

[0004] In the Chinese patent with publication number CN108819032A, a waste silicone rubber material recycling device is mentioned, which includes a first mounting plate, a bottom plate, a first collecting frame, a second mounting plate, a lower hopper, a butterfly bolt and a sliding sleeve, etc. The present invention achieves the goal of completely crushing the waste silicone rubber material, and the dust generated during the crushing process will not pollute the environment;

[0005] The waste silicone rubber recovery device in the above-mentioned prior art only crushes the waste silicone rubber once when recycling the waste silicone rubber. It is difficult to crush the waste silicone rubber completely by a single crushing, which results in the crushed silicone rubber fragments being of different sizes, and the larger fragments still carry dust and impurities inside, which affects the subsequent use of the recycled silicone rubber.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1-Figure 9 As shown, the present invention provides a waste silicone rubber recycling and processing system, comprising:

[0038] The outer shell 1 has a feeding hopper 6 for waste silicone rubber to enter at the top, four supporting columns 4 arranged in a rectangular shape are arranged on the outer side of the outer shell 1, and a discharge port 5 for discharging the crushed waste silicone rubber is arranged at the bottom of the outer shell 1;

[0039] The dust removal mechanism 3 includes a dust collection component and a feeding component. The dust collection component is arranged outside the housing 1 and is used to absorb and filter the dust when the waste silicone rubber in the housing 1 is crushed. The feeding component is arranged outside the housing 1 and is used to cooperate with the dust collection component to process the dust inside the waste silicone rubber.

[0040] The processing mechanism 2 includes a crushing component and a screening component. The crushing mechanism is arranged inside the shell 1, and is used to crush the waste silicone rubber entering the shell 1. The screening component is arranged on the inner side of the shell 1, and is used to screen the waste silicone rubber after being crushed by the crushing component, and cooperates with the feeding component to transport the large pieces of waste silicone rubber that have not been crushed to the crushing component for crushing again.

[0041] In a further embodiment, referring to Figure 1-Figure 4The dust collection component includes a filter box 304, which is fixedly connected to the outside of the shell 1. The inner side of the filter box 304 is movably connected with a transmission rod 306 through a bearing. The transmission rod 306 can rotate in the filter box 304. The right end of the transmission rod 306 is fixedly connected with a fan blade 309. When the transmission rod 306 rotates, the fan blade 309 can be driven to rotate. The rotation of the fan blade 309 can drive the air in the filter box 304 to flow outward, so that the filter box 304 is in a negative pressure state, and suction is formed through the L-shaped elbow 303 to suck the air in the shell 1. The inner side of the filter box 304 is fixedly connected with a filter screen 308. The filter screen 308 filters dust impurities and dust in the air entering the filter box 304. The top of the filter box 304 is fixedly connected with an L-shaped elbow 303 connected to the inside of the filter box 304. The filter screen 308 is connected with a bearing. The filter box 304 is provided with a protective net on the right side of the L-shaped elbow 303, which is used to facilitate the discharge of air and prevent the entry of debris.

[0042] Furthermore, before recycling the waste silicone rubber, the sealed loading container is connected to the discharge pipe 307 to ensure that air does not enter and exit through the discharge pipe 307, while also ensuring that dust and debris filtered by the filter 308 can enter the loading container through the discharge pipe 307, and the loading container is removed regularly for cleaning.

[0043] In this embodiment, while the driving motor 201 drives the crushing roller 204 to rotate, the fan blades 309 are driven to rotate through the active wheel 205, the driven wheel 305 and the belt, so that the dust impurities and dust generated when the waste silicone rubber and large silicone rubber particles in the shell 1 are crushed are sucked in and filtered, and the filter net 308 can be cleaned during the filtering process to ensure the filtering effect.

[0044] In a further embodiment, referring to Figure 6-Figure 7The feeding component includes a rectangular shell 301, which is fixedly connected to the rear side of the outer shell 1. A rotating rod 311 is movably connected to the inner side of the rectangular shell 301 through a bearing. The rotating rod 311 can rotate in the rectangular shell 301, thereby driving the spiral blade 312 to rotate in the rectangular shell 301. A stirring plate 317 is fixedly connected to the outer side of the rotating rod 311. A spiral blade 312 is fixedly connected to the outer side of the rotating rod 311. The spiral blade 312 is provided with two sections. The two sections of spiral blades 312 are symmetrically distributed on the outer side of the rotating rod 311. The outer side of the spiral blade 312 is adapted to the inner side of the rectangular shell 301. When there are large pieces of silicone rubber particles in the rectangular shell 301, the rotation of the spiral blade 312 can drive all the large pieces of silicone rubber particles to move upward and be discharged through the output pipe 316. The front side of the rectangular shell 301 is provided with an output pipe arranged in an inclined manner. 316, the end of the output tube 316 away from the rectangular shell 301 is arranged in an inclined shape, the end of the output tube 316 away from the rectangular shell 301 passes through the rear side of the shell 1 and extends into the inside of the shell 1, and is located between the two crushing rollers 204, a feed trough 315 is opened at the lower front side of the rectangular shell 301, the bottom end of the rotating rod 311 passes through the bottom of the rectangular shell 301, the bottom end of the rotating rod 311 is fixedly connected to the worm gear 2 313, the bottom of the rectangular shell 301 is fixedly connected to the servo motor 302, the servo motor 302 is fixedly connected to the worm 314 through the output shaft, the outer side of the worm 314 is meshed with the outer side of the worm gear, the servo motor 302 can drive the worm 314 to rotate through the output shaft, the rotation of the worm 314 drives the worm gear 2 313 to rotate, thereby driving the rotating rod 311 and the spiral blade 312 to rotate, so as to transport the large pieces of silicone rubber particles.

[0045] It should be noted that when the rotating rod 311 rotates, the lower spiral blade 312 will transport the large silicone rubber particles that have entered the rectangular shell 301 upward;

[0046] When the silicone rubber particles are transported to the upper part of the lower spiral blade 312, the silicone rubber particles located between the two spiral blades 312 are rotated by the rotating stirring plate 317. Under the stirring of the stirring plate 317, the dust carried by the large silicone rubber particles is shaken off;

[0047] As the number of large silicone rubber particles between the two spiral blades 312 increases, the large silicone rubber particles can be taken away by the rotation of the upper spiral blade 312. The rotation of the upper spiral blade 312 drives the large silicone rubber particles and dust to move upward until they are discharged through the conveying pipe 316. This design facilitates subsequent transportation to the crushing component so that they can be better sucked in by the dust collection component.

[0048] Furthermore, a through slot adapted to the feed slot 315 is provided on the rear side of the housing 1 , and the rear side of the through slot is connected to the front side of the feed slot 315 , so as to facilitate the transport of the large silicone rubber particles on the screen 206 into the rectangular housing 301 .

[0049] In this embodiment, the servo motor 302 can drive the rotating rod 311 to rotate through the worm 314 and the worm gear 313, so that the large silicone rubber particles entering the rectangular shell 301 are transported to the crushing assembly for re-crushing under the action of the spiral blade 312, which is convenient for handling the dust remaining in the large silicone rubber particles and ensures that the size of the crushed silicone rubber particles is uniform.

[0050] In a further embodiment, referring to Figure 3 and Figure 5 The crushing assembly includes a crushing roller 204. The two crushing rollers 204 are movably connected to the inner side of the shell 1 through bearings. The crushing rollers 204 are used to crush the incoming waste silicone rubber. The outer side of the shell 1 is fixedly connected to a driving motor 201. The output shaft of the driving motor 201 is fixedly connected to one of the crushing rollers 204 through a coupling. The driving motor 201 can drive one of the crushing rollers 204 to rotate through the output shaft, so that one of the crushing rollers 204 works. The outer sides of the two crushing rollers 204 are fixedly connected to transmission gears 203. The two transmission gears The opposing surfaces 203 mesh with each other. When one of the crushing rollers 204 rotates, the other crushing roller 204 can be driven to rotate through the two transmission gears 203. A driving wheel 205 is fixedly connected to the outer side of one of the crushing rollers 204. The outer side of the driven wheel 305 is connected to the outer side of the driving wheel 205 through a belt drive. The rotation of the crushing roller 204 drives the driving wheel 205 to rotate, and the driven wheel 305 can be driven to rotate through the belt to provide power for the operation of the dust collection component. The two are linked to each other, reducing the use of the motor, so that the device has good linkage.

[0051] Furthermore, a motor bracket 202 is fixedly connected to the outside of the driving motor 201 , and the motor bracket 202 is fixedly connected to the outside of the shell 1 . The motor bracket 202 is used to support and fix the driving motor 201 to ensure the stability of the driving motor 201 during use and continuously provide kinetic energy for the rotation of the crushing roller 204 .

[0052] In this embodiment, the driving motor 201 drives one of the crushing rollers 204 to rotate through the output shaft and the coupling, and the two crushing rollers 204 rotate simultaneously under the action of the two transmission gears 203 to crush the waste silicone rubber and large silicone rubber particles put in, so as to facilitate the subsequent utilization of the crushed silicone rubber particles. In addition, when crushing the waste silicone rubber and large silicone rubber particles, the dust adsorbed on the surface and inside thereof can be processed.

[0053] In a further embodiment, referring to Figure 3 and Figure 8-9The screening assembly includes a fixed rod 207, which is fixedly connected to the inner side of the shell 1. The outer side of the fixed rod 207 is movably connected to a screen 206 through a bearing. The fixed rod 207 is used to support one side of the screen 206, and the other end of the screen 206 can be movable under the action of the bearing. Two V-shaped inclined bars 210 are fixedly connected to the top of the screen 206. The ends of the two inclined bars 210 that are close to each other are not connected, but are arranged in an open shape, so that large pieces of waste silicone rubber particles on the screen 206 can enter the feed trough 315 through the through groove, and then enter the rectangular shell 301 through the feed trough 315. A spring 209 is fixedly connected to the bottom of the screen 206. Under the action of the spring 209, the screen 206 can shake under the push of the top block 214, thereby improving the filtering effect on the silicone rubber particles. A disc 213 is arranged at the bottom of the screen 206, and a top block 214 is fixedly connected to the top of the disc 213. The rotation of the top block 214 can intermittently push one side upward, and reset under the action of the spring 209, thereby forming intermittent shaking. The bottom of the disc 213 is fixedly connected to a vertical rod 212, and the vertical rod 212 is used to drive the rotation of the disc 213. The outer side of the vertical rod 212 is movably connected to a support bar 215 through a bearing. The support bar 215 is used for connecting the vertical rod 212 and the inner side of the shell 1. The support bar 215 is fixedly connected to the inner side of the shell 1. The bottom of the spring 209 is fixedly connected to a fixed block 208, and the fixed block 208 is fixedly connected to the inner side of the shell 1. The front end of the worm 314 passes through the rear side of the shell 1 and is movably connected to the rear side of the shell 1 through a bearing. The bottom end of the vertical rod 212 is fixedly connected to a worm wheel 211, and the outer side of the worm wheel 211 is meshed with the outer side of the worm 314. The rotation of the worm 314 can simultaneously rotate the worm wheel 211 and the worm wheel 2 313, thereby reducing the use of the motor and further improving the linkage of the various components in the device.

[0054] In this embodiment, the screen 206 filters the silicone rubber particles crushed by the crushing component. The silicone rubber particles that meet the size fall through the screen 206, and the large silicone rubber particles that do not meet the requirements are transported to the feeding component under the shaking of the screen 206, and then transported to the crushing component for crushing.

[0055] The working principle of the present invention is as follows:

[0056] The waste silicone rubber to be recycled is put into the feed hopper 6, and the start of the driving motor 201 drives the two crushing rollers 204 to rotate. The rotation of the crushing rollers 204 crushes the waste silicone rubber, and the crushed silicone rubber particles fall on the screen 206. The silicone rubber particles that meet the conditions pass through the screen 206 and are discharged through the discharge port 5 below. The large silicone rubber particles that cannot pass through the screen 206 remain on the screen 206.

[0057] The servo motor 302 drives the worm 314 to rotate through the output shaft, and the worm 314 drives the vertical rod 212 to rotate through the worm gear 211. The vertical rod 212 rotates to intermittently push the screen 206 to shake in the up and down directions through the disc 213 and the top block 214, and the large silicone rubber particles remaining on the screen 206 are sent into the rectangular shell 301 through the feed trough 315;

[0058] The worm 314 drives the worm gear 1 211 to rotate, and at the same time drives the worm gear 2 313 to rotate. The rotation of the worm gear 2 313 drives the rotating rod 311 and the spiral blade 312 to rotate, and drives the large silicone rubber particles in the rectangular shell 301 to move upward until they are discharged through the output pipe 316 to the top of the crushing roller 204 for re-crushing.

[0059] When the crushing roller 204 rotates, the driving wheel 205, the driven wheel 305 and the belt drive the transmission rod 306 to rotate, and the transmission rod 306 drives the fan blade 309 to rotate. The fan blade 309 rotates to extract the air in the housing 1 through the filter box 304 and the L-shaped elbow 303. The air in the housing 1 carries the dust, impurities and dust generated when the waste silicone rubber is crushed and enters the filter box 304 to be filtered and collected;

[0060] The above operation is repeated until all the silicone rubber particles are screened by the screen 206 and then stopped, completing the recycling of the waste silicone rubber.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
